But it misses a huge nuance on the whole "dystopian" thing. The main thing about "social score bad" takes is that the government will use that scoring. It's not private <-> private. Everything the author mentions about the various scoring in the US (and EU for that matter, although to a lesser extent in some cases) is between you and private institutions. The government does not "track" or "access" or "use" those 3rd party scores.
It's a bit like 1st amendment in the US. You have the right of free speech with regards to the government. That means the government cannot punish you for your speech. But that says nothing about your relationship with private parties. If you go to a government institution and tell them their boss sux, in theory you shouldn't be punished for that, and they'll keep serving you. But the same does not extend to a private bakery. Or a bar. Or any private property. Tell them their boss sux, and you might not get service.
So yeah, there are lots of 3rd party rating services. But they're mainly between you and those 3rd parties. The government mainly stays out.
